An Overview of the Webmail Interface in Carbonio Community Edition | Carbonio CE

Carbonio CE is an open-source fully featured private collaboration platform. It provides you with an email service along with contacts and calendars. It also has a file management system to edit and share them with your collaborators at the same time. You can access all these features at the same webmail interface. That’s why we are writing this article to give you a tour of the Carbonio Community Edition (Carbonio CE) webmail interface.

I assume you have installed the Carbonio CE in your virtual machine or physical server. If you did not do it yet, please install the Carbonio CE following the linked article.

Now, we have installed Carbonio CE (Carbonio Release 22.12.0) on a server. To access the web interface of Carbonio CE, you can use both the IP address or DNS name (If you have published one). In our case, we are using a DNS name ( to access our web interface.
